This invention relates to the construction for the hulls of steel vessels, and more particularly to the use of channels and plates in the construction of the hulls of vessels having the usual shaped pointed bow and rounded stern.

There are important advantages structing the hulls of vessels of channels, such for instance as no rivets passing through the shell and the flanges of the channels strengthen-the shell against indentation and also prevent buckling ofthe ves- ..sel. While it is desirable to construct vessel hulls of channels, it is difiicult and expensive to make channels conform to the shape necessary in forming the bow or stern and spending parts.

Figure 1's a side elevation of the hull 4 of a steel vessel constructed in accordance with my invention,

Fig. 6 is a cross sectional view taken on line 6-6 of Fig. 3.

Referring to the drawings 1 represents a plurality of channels of standard construction, which are connected together at their flanges by rivets or bolts or in any other suitable manner as indicated at 2. The channels are connected together at their adjoining ends by butt straps 3 or in'any other suitable manner, and the channel construction graduallyincreases in length from the bottom 4 towards the top ofthe hull. The forward portion of the upper channels are curved inwardly as shown at 5. Plates 6 overlap the outer sides of the upper channel in contion of the "modifica- 7, and the forward plates thereof, as indicated by 8, are curved inwardly to form the bow, while the rear plates 9 are curved to form the stern of the hull of the vessel.

Plates of suitable width and length, as

indicated by 10, overlap the forward ends.

of the channels 1 at 11 and the upper one of these plates the lower longitudinal porplate 8, and these plates are curved to form the desired shape of the bow, and plates 12 overlap the rear ends of the channels 1 at 13 and the upper ones of these plates the lower longitudinal portions of. the

plates 9, and these plates are suitably curved to form the stern of the hull of the vessel.

The deck of the. vessel, indicated by 14, is constructed of plates or channels, the side edges of which are supported by angle bars 15, which are connected to the side plates 6, Sand 9. Said deck is located at a suitable distance below" the upper edge of the plates 6, 8 and 9, so that the upper portions of said plates provide a gunwhale or inclosure for the deck.- Plates indicated by 16 and 17, are connected to the plates 6, 8 and 9 and form the bulwarks' at the forward and rear ends of the vessel.

The joints between the various plates may' be constructed by overlapping as at 11' and 13 or by means of butt straps asat 18 according to location and desire.

, Instead of employing the plates 16 and 17 to form the bulwarks, channels indicated .by 19 may be employed for forming the bow of the vessel and channels 20 for the stern. These channels are out ofi on a curve as indicated at 21 and 22 respectively and are curved inwardly'to proper form for the bow and stern, and their adjoining ends are connected together by butt straps as at 23 or in any suitable manner. The deck is formed of channels 24 or plates. which are'cpnnected It will be of channels, forming the sides of the hull intermediate the ends thereof, and plates connected to said channels forming the ends of the hull. a

2. In a hull for- Vessels, the combination of channels, the channels being chnnected together at their flanges for forming the sides of the hull intermediate the ends thereof plates connected to the ends of said channe s, and said plates being curved to form the bow and stern'of the hull.

In a hull for vessels, the combination of channels, the channels bein connected together at their flanges for forming the sides of the hull intermediate the ends thereof; plates connected to theends of said channel's, forming the bow and stern, and

plates connected to the u vper channel and the upper plates of said p ates forming the bow and stern. I

4. In a hull for Vessels, the combination of channels forming the sides of the hull intermediate the ends thereof, plates connected to the ends of-said channels forming the bow and stern, plates connectedto the upper channel and the upper plates of said plates forming the bow and stern, and :1 deck supported by the last mentioned plates In testimony whereof I atfix my signa ture.
